Use prepositions as adjectives or adverbs. Avoid ending a sentence with a preposition.
A Preposition is a word used to show the relation of a noun or pronoun to some other word in the sentence.
In the following sentences the prepositions are shown in bold type. The words between which the prepositions show relationship are italicized.
A preposition always introduces a phrase. The noun or pronoun at the end of a prepositional phrase is the object of the preposition which begins the phrase. In the preceding examples the objects of the prepositions are street, lunch, car, line, and clouds.
Prepositional phrases are used as adjectives (modifying a noun or pronoun) or adverbs (modifying a verb, adjective or adverb). Adverbs answer the questions where, when, how, or to what extent.
The following words are commonly used as prepositions:
